Getting Ready to Start: A Step-by-Step Guide
Before attempting to fire up your Briggs and Stratton lawn mower, it’s crucial to prepare the machine and the environment for a successful start.
1. Safety First: Prepare the Area
- Level Ground: Make sure your mower is parked on a flat, level surface. This prevents accidental rolling and ensures the engine runs smoothly.
- Clear Surroundings: Remove any obstacles, such as toys, tools, or plants, from around the mower’s operating area.
- Safety Gear: Always wear safety glasses, sturdy closed-toe shoes, and long pants when operating a lawn mower.
2. Check the Fuel Level and Fuel Valve
- Fuel Gauge: Check the fuel gauge on your mower to ensure you have enough fuel. If the gauge is unclear, it’s best to add fuel to be on the safe side.
- Fuel Valve: Locate the fuel valve (often a red knob or lever) and make sure it is in the open position. This allows fuel to flow from the tank to the carburetor.
3. Oil Level Check
- Oil Dipstick: Locate the oil dipstick, usually found on the side of the engine. Pull it out, wipe it clean, and reinsert it fully.
- Oil Level: Remove the dipstick again and check the oil level. It should be between the “Full” and “Low” marks on the dipstick. If the oil level is low, add oil to the appropriate level.
4. Prime the Carburetor (If Necessary)
- Primer Bulb: Many Briggs and Stratton models have a primer bulb, usually located near the carburetor.
- Priming: Press the primer bulb several times to fill the carburetor with fuel. This is especially important when starting a cold engine or after the mower has been sitting for an extended period.
Starting the Engine: From Choke to Throttle
With the necessary preparations complete, it’s time to tackle the actual starting process:
5. Engage the Choke
- Choke Lever: Locate the choke lever, usually a small lever on the engine. This lever restricts air flow to the carburetor, enriching the fuel mixture for easier starting.
- Choke Position: Engage the choke fully. This is often a “choke” or “fast idle” position on the choke lever.
6. Pull the Starter Cord
- Starter Cord: Locate the starter cord handle, usually on the top of the engine.
- Pulling Technique: Grip the handle firmly and pull the cord slowly until you feel resistance. Then pull quickly and firmly. Avoid jerking the cord too aggressively.
7. Release the Choke
- Warm Engine: Once the engine starts, slowly release the choke lever.
- Steady Idle: The engine should continue running smoothly as you release the choke.
8. Adjust the Throttle
- Throttle Lever: Locate the throttle lever, usually found on the handlebar or side of the engine.
- Throttle Position: Adjust the throttle to the desired speed for mowing.
Troubleshooting Common Starting Problems
Even with the most careful preparation, you may encounter difficulties starting your Briggs and Stratton lawn mower. Here are some common issues and their solutions:
1. Flooded Engine
- Symptoms: The engine sputters, coughs, or refuses to start even after repeated attempts.
- Solution: Release the choke and pull the starter cord several times with the choke fully disengaged. This helps clear out excess fuel.
2. Difficulty Starting in Cold Weather
- Cold Start Issues: Engines tend to be more difficult to start in cold temperatures due to thicker oil and decreased fuel volatility.
-
Solutions:
- Primer Bulb: Use the primer bulb to add extra fuel to the carburetor.
- Choke: Engage the choke fully and give the starter cord a few extra pulls.
- Warm-up: Once the engine starts, allow it to run for a few minutes before engaging the throttle and mowing.
3. Spark Plug Issues
- Spark Plug Check: Remove the spark plug from the engine.
- Spark Plug Condition: Inspect the spark plug. If it is cracked, corroded, or has excessive buildup, it should be replaced.
- Spark Test: If the spark plug is in good condition, test it by holding it near the engine block and pulling the starter cord. A strong, blue spark should appear.
Maintaining Your Briggs and Stratton Lawn Mower for Optimal Performance
Regular maintenance is essential for ensuring your Briggs and Stratton lawn mower runs smoothly and lasts for years to come.
1. Fuel Stabilization
- Fuel Degradation: Gasoline can degrade over time, even when stored in a sealed container.
- Fuel Stabilizer: Add fuel stabilizer to the gas tank to prevent fuel from going bad.
2. Regular Oil Changes
- Oil Degradation: Engine oil breaks down over time, reducing its effectiveness and potentially damaging the engine.
- Oil Change Frequency: Check your owner’s manual for recommended oil change intervals.
3. Air Filter Cleaning
- Air Filter Function: The air filter prevents dust and debris from entering the engine, protecting it from damage.
- Air Filter Cleaning: Clean or replace the air filter regularly, according to the manufacturer’s instructions.
4. Blade Sharpening
- Dull Blades: Dull blades can cause uneven cuts and damage your lawn.
- Blade Sharpening: Sharpen the blades regularly, or have them sharpened professionally.
